Obesity,resulting from an imbalance between energy intake and expenditure,represents a major health crisis to our society,due to its alarmingly high preva-lence and comorbidities,including dia-betes,cardiovascular diseases,cancer,and COVID-19.Better understanding the neurobiological mechanisms for feeding behavior is essential for developing ra-tional strategies to combat obesity and related comorbidities.

结合法律规范与实务反馈,认罪认罚从宽制度适用于自诉案件审判领域,既有合法性依据,又有现实性基础,这种实践方案具有鲜明的司法特色.在对77份一审刑事判决书进行分析的基础上,探讨自诉案件认罪认罚从宽制度的完善方案如下:第一,明确自诉案件认罪认罚的成立标准;第二,辨析认罪认罚情节的刑事法律评价效力;第三,规范审判阶段自诉案件认罪认罚程序;第四,保障当事人获得有效的专业法律帮助;第五,提高自诉案件审判活动的检察监督质量.
在中国的正史系统中,绝大部分正史都有专门的民族列传,但南北朝时期的北齐和陈存在的时间短、辖境小,在《北齐书》和《陈书》中就没有专门的民族列传.因此,民族史学界对北齐和陈的民族历史研究不多,研究成果也很少.实际上,在《北齐书》《陈书》的相关本纪、列传中都有诸多的民族交往交流交融的记载.值得注意的是,北齐和陈与相关民族的交往交流交融具有方向性特征,北齐和北方及东北地区的民族交往交流交融比较多,陈主要是和辖境内的山越、僚人进行交往.陈与海外民族的交往,则主要集中在东北亚和东南亚地区.
The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway senses the presence of cytosolic DNA and,in turn,triggers downstream signaling to induce the expression of inflammatory and type Ⅰ interferon genes in immune cells
Microtubules consisting of α/β-tubulin dimers play critical roles in cells.More than seven genes encode α-tubulin in vertebrates.However,the property of microtubules composed of different α-tubulin isotypes is largely unknown.Here,we purified recombi-nant
The tumor suppressor p53 plays an important role in the inhibition of cancer progression,particularly in response to chemotherapy or target-specific therapy.Inactivation or mutation of p53 often becomes a cancer\'s tactic for drug resis-tance.One of the
18S,5.8S,and 28S ribosomal RNAs (rRNAs) are cotranscribed as a pre-ribosomal RNA (pre-rRNA) from the rDNA by RNA polymer-ase I whose activity is vigorous during the S-phase,leading to a conflict with rDNA replication.This conflict is resolved partly by re

在农村发展的过程中,很多地区陷入了“有增长无发展,投资低效益”的内卷困境.华北燕城村项目进村实践过程中,存在着“无用、不实用,不及时、不落实,不适用、不科学,有前劲无后劲”等问题,使得大量的投入低效运转,造成资源浪费.农村发展中的低效内卷困境,说到底其实是治理的低效困境.治理的低效只是表象,治理的异化才是背后真正起作用的“暗力量”.治理主体、治理关系、治理方式、治理目标的异化反映了乡村治理所依托的微观政治社会系统内部的病症,需要引起高度警惕.
青海位于准噶尔与西藏往来的交通要道,具有重要的军事意义.雍正帝征讨准噶尔期间,在青海进行了严密的战略部署,调兵驻守青海要地噶斯并特派大臣驻西宁管理军务,在西宁多备兵力,采买和转运军需,青海蒙古亦参与其中担任向导、驻防台站.清朝在青海的军事计划为清军提供了充足的兵力援助和军需补给,防守青海要地阻止了准噶尔觊觎西藏、青海,保证了清军侧翼的安全,有利于清朝西北边疆的稳定.
